Bifurcated endograft in aortoiliac type C and D lesions: long-term results.

PURPOSE To report long-term outcome when using a bifurcated aortic endograft for treatment of aortoiliac occlusive disease (AIOD) in Trans Atlantic Inter Society Consensus (TASC) classification C and D patients. MATERIALS AND METHODS Between May 2001 and May 2009, 14 patients (11 men, 3 women) with aortoiliac TASC C and D type lesions and a mean age of 59 years ± 10 (range 41-73 years) were treated using a bifurcated aortic endograft. Although these patients were young, all were considered at high surgical risk. Patients were followed up clinically and by computed tomography (CT) every 3 months for 1 year and yearly thereafter. RESULTS Endoprosthesis placement was performed in all patients with a technical success rate of 100%. There were no amputations or deaths at 30 days after the procedure. The mean follow-up was 62 months (range 11-96 months). One patient was lost during follow-up at 11 months, and another patient died of a nonrelated cause after 49 months. A single limb occlusion of the prosthesis was seen in two patients at 2 months and 7 months; both were successfully treated by intraarterial fibrinolysis. At a mean follow-up of 62 months, primary patency was 85.7%, and secondary patency was 100%. CONCLUSIONS This series shows promising long-term results following the use of a bifurcated aortic endograft for treatment of AIOD TASC C and D type lesions. Bifurcated aortic endograft is a good minimally invasive alternative to open surgery in high surgical risk patients.
